查询词典 sound track

With STTIN, Basic properties of wheel/rail noise of embankment ballasted track are investigated.

与有碴轨道相比，板式轨道噪声显著增大，其中钢轨近旁噪声高出6.2dBA左右，铁路边界处近地面噪声高出约3.5dBA；桥上支承块式无碴轨道轮轨噪声比有碴轨道的要大，其中钢轨近旁噪声大2.8～4.5dBA，桥面正下方0.3m处的噪声大1.4～2.3dBA。

The results show that the vehicle acceleration, the dynamic wheel load and offload factors increase with train speed, and distribute linearly. The safety of train operation and running comfort can meet the requirements when the high-speed train under secondary suspension passing through ballasted track subgrade structure. The dynamic displacement of the system is less influenced by train speed. The dynamic stress of subgrade surface increases with speed improving, and it is distributed as saddle along the lateral direction and as parabola along the longitudinal direction of subgrade surface. The dynamic stress of subgrade declines sharply along the depth of subgrade. The dynamic stress on 3 m depth below subgrade bed surface is about 16 percent of that of subgrade surface.

结果表明：车体加速度、动轮载和轮重减载率均随车速的提高而增大，呈线性分布；具有二系悬挂的高速列车通过有砟轨道路基结构时，列车的安全性及舒适度均能满足要求；系统动位移受速度影响较小；路基面动应力随速度的提高而增大，并在横向呈马鞍形分布，在纵向呈抛物线形分布；路基动应力沿路基深度方向衰减较快，在基床表面下3 m处，动应力只有基面的16%左右。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
